The Ronin-S Multi-Camera Control Cable, for the Sony multi-port, from DJI, allows you to connect a Sony camera with a multi-port connection to the Ronin-S gimbal's camera control port. Then with the gimbal's camera control button you can control aperture, autofocus, and recording start/stop. Also, if you use a compatible lens with built-in power zoom, such as the Sony E PZ 18-105mm F4 G OSS lens, you'll be able to use the gimbal's focus wheel to control optical zoom. With other lenses, the focus wheel will control digital zoom (digital zoom will need to be enabled in the camera's settings).
All DJI brand products are non-returnable after any packaging has been opened.
